AJUAN SAUS, F BA CARD . Application ined April 24,

l ments Relating to Carding, of which the following is a specification.

There are two existing methods of wool spinning, namely (l) in which the material is prepared by carding, applied to short bers which cannot be rendered parallel and as a consequence the threads obtained are soft to the touch but they cannot be spun to a very low number, and (2) in which the material is prepared by combing. applied to the bers for rendering them parallel in which the short fibers, that is lthe noils, are separated, the threads obtained being vne` but hard to the touch by reason of the short bers having been eliminated.

' It will be understood that it isv amatter of industrial imp'ortance to obtain wool bers *which while having the supple feel of threads of short ber have a degree of neness such as given to-threads formed only of long bers because with the threads thus obtained one is able to produce as fineproducts on weaving looms as those actually produced with threads of wool having longk bers and without presenting to the touch the hardness of these latter. To obtain this new result it is necessary to have a method and machine permitting of spinning together two sorts of ber long and short.

According to the yinvention this result is secured by 'a carding operation. The method of carding is applicable particularly to the treatment of wools because 'of its utility vwith respect to fibers of mixed lengths without it being necessary to separate the bersfaccording to length. Accordingly the invention consists in spinning previously or naturally mixed long wo'ol and short wool by which is obtained the suppleness, regularityand neness of thread `and that at a reduced cost since according to the invention the wool can be treated by the parallelization` of the bers without fit being necessary to separate the short fibers, that is the noils.

Accordingly a machine such as that em-y ployed for carding short bers is combined with a means for drawing or stretching ribbons or sections resulting from the division of the lap and the combingof the same ribbons for compietingA theV parallelization of the 'bers they are passed' between' Specification of Letters Patent TED .ST Es f f f RCEL'ONA, sPAiN.

condensing rubbers or aprons. This opera i tion is produced'by mechanism represented 1n Fig. 3 of the accompanymg drawings,

but in order to secure the desired effect it is necessary to obtainl inthe passage ofthe .l

bers into 4and through the carding machine` a perfect distribution of they bers and this effect is realized by the mechanism represented in Fig. l. g v

In the accompanying drawing,

Figure l is a diagrammatic planview of a machine comprising the necessary modications to the present invention.

l Fig. 2 is a front view of a feeding arrange-` ment for the machine, while -i Fig. 3 is a sid-e View in section on a large i' scale of mechanism for perfectingthe ribbons andV rendering them uniform. The mechanism illustrated in Fig. 3- replaces on the machine the mechanism ordinarily em-` l i ployed for the formation yand withdrawal of the slivers.

Fig. 4 is a side elevation and Fig. 5 a 'detail end elevation -illustrating the known mechanism for imparting a movement tothe drum 9. v

`The feeding arrangement of the carding machine consists of two ribbon guides or funnels 1 and 2 which are given a reciproreciprocating eating rectilinear movement vin a direction parallel to that of the axis of the main cylinder 3 of the carding machine, the movement being reciprocating with-strokes such that the guide or funnel lV passes over one part of the front of the cylinder 3,'.while the guide.

or funnel 2 passes over the remainder of the front of the cylinder.

The isliversof ber whiclrare of mixed lengths, say of wool, to separate .the bers of which, according to length, no .attempt has been made, passingthrough the guides and funnels 1 and 2 come respectively Afrom bobbin's 4 and 5 which follow the movementsA of the guides or funnels, for which purpose they are mountedon carriages 6 and'7 connected one with the other by the plate 7* (see the front elevation Fig. 2) actuated by traction chains 8 and 8. These chains are xed by one of their extremities tothe carriages 6 and 7 and pass onto the drum 9, guided by the pulleys 10 andll respectively.

The known mechanism for imparting a..

- l and of the wheel c rock upon the spindle interrupted by a slot g. A part h uponwi which two guides i and Z are formed is pro- Y vided at the place corresponding with the slot g. .As a result of this arrangement, when the pinion d has traversedV the teeth of one of' the faces of the plate f, it passes through the slot g,the `gud'geon of the pinion sliding over one of theguides-z' or Z and then passes over the teeth'on the other face of the plate.

The shaft m on which the drum 9 is keyed' is thus given a reciprocating movement of rotation.

-It will be understood that the ribbons on yleaving the bobbi-ns 4 and 5 pas-s through feed rollers to the licher-in roller, the carding machinebeing the same as is usual except' 4for the additio-n of the mechanism illustrated'in Figs. 1 and 3.

In this manner the ribbons are uniformly distributed over the main cylinder 3 each over its own end, this` uniformityis` increased and perfected in the known manner by the action of a cylinder 12 covered with card points in thevsame manner as the cylinder 3', the cylinder 12 having a movement ofrotation and at the same time a' reciprocating movement, produced by the cam 13. i

By the means described a perfectly uniform lap is produced with the fibers lying parallelthroughoutwits length. In the same carding machine the lapis divided in a known manner into sections or parts each of which is subjected tothe action of the device represented in vertical section in Fig. 3. Each card comprises a number of these devices equal to the number of sections into which the lapl is divided. These lsections are formed into ribbons by ltheir passage through'l the guides or funnels 14 and are subjected tothe action of .pressure rollers 15, 16. They are ythen drawn or stretched between. these rollers and other rollers rotating aty a higher surface velocity. y Of these rollers,fthe roller 17 isprovided with comb points while the rollers 18 and 19 are fluted longitudinally. At 20 is mounted a roller covered with leather so that it may fit snugly against the iiuted rollers 18 and 19.

In order'to imparta certain consistency to the ribbons they are passed through rubbers 21', 22 after which they pass through guides 23 and are rewound upon rollers 24.

In practice, carding by the method described is'eiiected con]ointly or in combination with the rest of the operations necessary in spinning. Although it has been relferred to as applied to the treatmentiof wools, obviously it is applicable to the treatment of other textile fibers but nevertheless its ,principal application is to wool.
